    void        xsltApplyStripSpaces            (xsltTransformContextPtr ctxt,
                                                 xmlNodePtr node);

Strip the unwanted ignorable spaces from the input tree

`ctxt` : | a XSLT process context
`node` : | the root of the XML tree

### xsltApplyStylesheet ()

    xmlDocPtr   xsltApplyStylesheet             (xsltStylesheetPtr style,
                                                 xmlDocPtr doc,
                                                 const char **params);

Apply the stylesheet to the document NOTE: This may lead to a non-wellformed output XML wise !

`style` : | a parsed XSLT stylesheet
`doc` : | a parsed XML document
`params` : | a NULL terminated arry of parameters names/values tuples
Returns : | the result document or NULL in case of error

### xsltProfileStylesheet ()

    xmlDocPtr   xsltProfileStylesheet           (xsltStylesheetPtr style,
                                                 xmlDocPtr doc,

                                                 FILE *output);

Apply the stylesheet to the document and dump the profiling to the given output.

`style` : | a parsed XSLT stylesheet
`doc` : | a parsed XML document
`params` : | a NULL terminated arry of parameters names/values tuples
`output` : | a FILE * for the profiling output
Returns : | the result document or NULL in case of error

### xsltRunStylesheet ()

    int         xsltRunStylesheet               (xsltStylesheetPtr style,
                                                 xmlDocPtr doc,

Apply the stylesheet to the document and generate the output according to `output` `SAX` and `IObuf`. It's an error to specify both `SAX` and `IObuf`.

NOTE: This may lead to a non-wellformed output XML wise ! NOTE: This may also result in multiple files being generated NOTE: using IObuf, the result encoding used will be the one used for creating the output buffer, use the following macro to read it from the stylesheet XSLT_GET_IMPORT_PTR(encoding, style, encoding) NOTE: using SAX, any encoding specified in the stylesheet will be lost since the interface uses only UTF8

`style` : | a parsed XSLT stylesheet
`doc` : | a parsed XML document
`params` : | a NULL terminated arry of parameters names/values tuples
`output` : | the URL/filename ot the generated resource if available
`SAX` : | a SAX handler for progressive callback output (not implemented yet)
`IObuf` : | an output buffer for progressive output (not implemented yet)
Returns : | the number of by written to the main resource or -1 in case of error.

Apply the stylesheet to the document and generate the output according to `output` `SAX` and `IObuf`. It's an error to specify both `SAX` and `IObuf`.

NOTE: This may lead to a non-wellformed output XML wise ! NOTE: This may also result in multiple files being generated NOTE: using IObuf, the result encoding used will be the one used for creating the output buffer, use the following macro to read it from the stylesheet XSLT_GET_IMPORT_PTR(encoding, style, encoding) NOTE: using SAX, any encoding specified in the stylesheet will be lost since the interface uses only UTF8

`style` : | a parsed XSLT stylesheet
`doc` : | a parsed XML document
`params` : | a NULL terminated arry of parameters names/values tuples
`output` : | the URL/filename ot the generated resource if available
`SAX` : | a SAX handler for progressive callback output (not implemented yet)
`IObuf` : | an output buffer for progressive output (not implemented yet)
`profile` : | profile FILE * output or NULL
`userCtxt` : | user provided transform context
Returns : | the number of by written to the main resource or -1 in case of error.
